Weight Fine-Tune; View Adc Output Code - CAS CI-100A Operation & Service Manual

13. Weight Fine-tune

With this function, the user can adjust displayed weight a little, and no need standard weight. But please
Note:
(1)The scale must have been calibrated before this adjustment
(2)The range of adjustment is "(current displayed weight) x (0.9-1.1)". it means the range is about ±10%
(3)The "CONFIG-REGULA =NONE" and "CONFIG-FUNC-WT.ADJ=YES" must be set.
(4) Only an authorized manufacturer's representative or certified verification personnel may make
these changes. Changing this value alters the calibration values !!!
13.1 To enter this mode, turn on indicator, after indicator displaying 0 weight, put a load (suppose: its correct
weight is 1230.0lb) onto scale, then indicator will display the load's weight, say "1234.5 lb". Press down
TARE and ZERO at same time until first digit flashes, this means indicator has entered into "weight
fine-tune" mode.
13.2 Use
weight will be displayed and no any digit will be flashed. After this, displayed weight will be adjusted by
this ratio (1230.0/1234.5) and this ratio will keep active until next modification on it.
13.3 To remove effect of this ratio, there're two ways: "12.3.1 way" and "12.3.2 way"
13.3.1 Do standard calibration, like in "12.CALIBRATION"
13.3.2 Move away weight on scale, Press ZERO to make 0 displayed, Put a load onto scale, a number
will be displayed, suppose it's 1230.0lb (but original number is 1234.5) ; Press down TARE and
ZERO at same time until first digit flashes, this means indicator has entered into "weight fine-tune"
mode.
Press
and exit to normal weighing mode.

14. View ADC output Code

14.1 In this mode, you can examine the stability of weighing system, the increment value of ADC output code
corresponding to the loaded weight.
Note:
① The increment of ADC code for FS weight must be larger or equal to 10 times of selected display
division; otherwise, the calibration cannot be properly completed. e.g. The display division is 0.1kg.
Load 100kg standard weight on the platform, the increment of ADC code should be at least more than
10x100kg/0.1kg= 10x1000=10000. In this case, the scale can be calibrated. Otherwise, smaller
division needs to be Chosen.
② The variation of ADC code should be small; otherwise, the calibration cannot properly complete also.
14.2 To go to this working mode, press down SETUP until CONFIG is shown, using PRINT , ACC and TARE
key to to go to MISC - Code item, press TARE to enter this mode and display ADC output raw code.
14.3 In this mode, first press TARE key can set current code as a reference zero, and then to display net code,
press TARE again to clear this reference and display gross code.
14.4 In this mode, press UNIT key to select displaying code that has been filtered by no-filter, filter1 or filter1
and filter2, and corresponding announciator Lo, OK, HI will be lighted.
14.5 Press SETUP key to return to last menu item, press ON/OFF key to prepare to exit this mode
────────────────────────────────────────────────────────
to input correct weight (1230.0). After confirmed by TARE, the active correct
key, the displayed weight will be restored to 1234.5, and then press
